Last night I set the car down and had a bit of a look.....I think it needs wider tires. It currently has 285s on 10.5" wheels which are a little wide for those tires I think.... but man it sure looks like a 315 on an 11" wheel is doable ......which means I think the order needs to be pick a tire size, pick a wheel, fit the antiroll bar. Over on the grassroots site I got pointed to Coleman and speedway racing as sources of off the shelf antirollbars that seems cheaper that I could make one...and I don't have to make it.

So a sent a link to the GRM thread to a buddy I worked with WAY back when I first got this car and the response was basically WTF are you using for wheel Studs? (a couple of the brake upgrade pics show home made wheel studs) Me - remember, these are the studs Al made for me when I didn't have a proper shop, to fit the aftermarket wheels I put on back then" Buddy - Dude....that's not safe! Get me the specs and I'll get you proper bolts! me- What? Buddy - I have a Ti bolt company now, Ti64. We make stuff like proper wheel bolts for all kinds of race teams that aren't just waiting to break like the ones I see in the pic....you can't use those you dumb a$$ (my translation) me - Sweet! ....now I need to figure out what I'm doing for wheels and somehow magically get my wife to approve the spending of money I probably don't have so I can tell Greg what bolts I need. Before I pull the engine I need to remove the rear springs so I can cycle the rear suspension and see exactly what will fit width wise, where it would put the antiroll bar, maybe even actually right some of it down so I only need to do this once. I guess that's the next step. |

And I wonder...should I be thinking about changing the front spindles? hmmmm...... |

On the rear I measure 34" to the outside of the frame. I read add 3" for arms and collars....so the super common 37" seems right. Up front it like 30" outside frame....but space is tight. Maybe like 32 and collars on the inside of the mounts...maybe

If you're looking at a large bar, then your roll rate and jounce rate are going to be significantly different. Dampers can only match one. |

Stupid everything has to match to work right I'm really not sure where optimal is exactly. I know the balance was not everything it could be and there seems to be more roll than seems optimal so my thought was to do something with the bars then move to the springs, then damping rates and see what I have. .....maybe....but I need the engine running to test anything |

I kind of have myself talked into piecing together something from here or similar http://1speedway.com/index.php?route=pr ... ry&path=76 like a 1"x.095 wall in the rear: http://1speedway.com/index.php?route=pr ... duct_id=90 then there is a good selection of gun-drilled 1 1/4" for the front but only in 1 length of 37 1/2"...but I remember thinking it would work http://1speedway.com/index.php?route=pr ... duct_id=89 so very light compared to solid bars.....I just need a running engine more at the moment. |

Oh yeah, I forgot you know the Ti64 dude. I re-discovered them and have been thinking about snagging a few bolts from them. A pair of Ti 5/8" bolts in each rear strut should save me about 1 lb of unsprung weight per rear corner. I'm thinking of titanium clutch cover bolts to reduce engine speed rotating mass and using Ti in the Northstar external case half locations just for S&Gs. |

I'm starting to think you like the fiero more than you like your ferrari....... |
